“Without being a trained climate scientist, I can read the various blogs and try to parse the academic papers, but ultimately I have to rely a lot on the good faith and judgment of the scientists themselves. The Heartland affair has reassured my earlier conviction that the case for climate alarmism is far weaker than the alarmists have been telling us.”

As an economist who has done some research on climate change policies, I am often asked questions along the lines of, “Is the science right or is it really a hoax like Rush Limbaugh says?” My standard reply is to acknowledge first of all that I’m not trained in the field, but to say that from my outsider perspective, it seems that the people warning of imminent catastrophe are vastly overrating the likelihood of their dire forecasts.…

The Wall Street Journal‘s Marketplace headline of March 5th said much: “Natural Gas to Power Pickups.” The piece did not mention the Nat Gas Act or other special government favors, just an effort by U.S. automakers to get natural-gas-fueled trucks into the mix given the large BTU disparity between gas and gasoline/diesel prices.

Reporter Jeff Bennett described a “growing wave” of interest in natural gas trucks:

On Tuesday, Chrysler Group LLC plans to disclose it will build the first production-line pickup truck powered by natural gas. The auto maker is promising to build at least 2,000 heavy-duty Ram bi-fuel trucks that run on a combination of compressed natural gas and gasoline starting in June.

General Motors Co. on Monday plans to disclose it will offer bi-fuel Chevrolet Silverado and GMC Sierra 2500 pickups in the fourth quarter.

“What happens to the millions of used CFLs that are tossed out in the trash each year? Chances are a large percentage are broken by users at home or are broken when compressed in the trash truck or compacted in a landfill. Regardless, the mercury contained in the bulbs is released to the environment.”

“My research found, much to my surprise, that both emissions—from [power plant] stack gas or broken compact fluorescent lighbulbs (CFL)—produce about the same magnitude of mercury release.”

President George W. Bush signed the Energy Independence and Security Act of 2007 with the words: “New technologies will help usher in a better quality of life for our citizens.”…

Last month, a group of 15 climate scientists (included the now disgraced Peter Gleick) sent a letter to Congress expressing their displeasure over the proposed Keystone XL Pipeline. President Obama has weighed in against approval, but Congress wants a green light to allow construction of the 1,700-mile, $7 billion project. Most recently, Bill Clinton weighed in for the pipeline, indicating just how deep the positives of the project are for the U.S. and world oil market.

So why are physical scientists getting political about a market-friendly pipeline to deliver oil from the Athabascan oil sands in Alberta, Canada, to various refinery locations in the Midwestern U.S. and ultimately the Gulf Coast?

The letter (reprinted at the end of this post) states that in addition to the local environmental impacts of oil sand mining (see here and here for a first-person account from Reason magazine’s Ron Bailey of the operation), burning such oil “on top of conventional fossil fuels will leave our children and grandchildren a climate system with consequences that are out of their control.”…
